TECHNICAL FIELD

Embodiments of the system and method generally related to computer server systems. More specifically, embodiments of the system and method generally relate to computer server systems with a flexible configuration.

BACKGROUND

A computer server system may be required to operate in a variety of different applications. The arrangement of the system components, also called the system architecture, can be flexible through the use of cables and/or switchboards. However, the use of cables and switch boards causes several problems. The use of cables to connect various system components is inefficient and expensive due to the cost of cables and engineering their installation. The use of cables also requires routing the cables within the system, taking up space that otherwise could be used for components. Cables also negatively impact the air flow within the system, resulting in less effective cooling of the system components and more energy required to properly cool the system. Service of the system is also impaired having to deal with a large number of cables that must be disconnected and reconnected in order to change the system configuration.

SUMMARY

This disclosure provides a system and method of a flexible configuration for a server system. A connector array engages a first switch board and optionally a second switch board. At least one central processing unit (CPU) and at least one peripheral device connect to the switch boards and the connector array. Through the arrangement of the switch boards on the connector array, a number of configurations of CPUs and GPUs and other components can be achieved, without rearranging cable. By disengaging and reengaging at least one of the switch boards in the connector array, additional configurations of components can be achieved, allowing a user to quickly and easily reconfigure the server system by only replacing at least one switch board in the connector array. By treating the switch boards as jumpers, a number of configurations can quickly and easily be accomplished, without the use of cabling and a plurality of connectors. A variety of other components may also be connected through the switch board, including but not limited to network cards and redundant array of inexpensive disks (RAIDs).

In some aspects, a flexible server configuration system includes a connector array including a plurality of slots and a first jumper board configured to removably engage with the connector array by connecting to a first set of consecutive slots from the plurality of slots.

FIG. 1 illustrates a block diagram of an example flexible server configuration system 100 with a one-node, two-CPU configuration. A first jumper board 102 (e.g., a six-port PCIe (Peripheral Component Interconnect Express) jumper board) is engaged in the first six board-to-board connectors (slots) of a connector array 108 (e.g., a PCIe×16 connector array). A second jumper board 104 is engaged adjacent to the first jumper board 102 in the connector array 108. Note that each of the first jumper board 102 and the second jumper board 104 can be disengaged from the connector array 108 and reengaged with any of the slots of the connector array 108. Each of the jumper boards 102, 104 also include a multiplexer/switch 106, as is known to those of skill in the art.

The first jumper board 102 is connected to a first network interface card (NIC) 114 via the first of the six slots connecting the first jumper board 102 to the connector array 108. The second of the six slots is connected to a first multiplexer 122 of Node One 118. Node One 118 includes two CPUs 126, 128. CPU1 126 of Node One 118 is connected to the first jumper board 102 via the first multiplexer 122. In this configuration, the first multiplexer 122 prevents the CPU0 128 from connecting to the first jumper board 102, by selecting CPU1 instead. The remaining four slots of the connector array 108 connected to the first jumper board 102 are in communication with a first GPU array 110.

The second jumper board 104 is engaged adjacent to the first jumper board 102 and engaged in the connector array 108 and is connected to the seventh through twelfth slots of the connector array 108 (from left to right).

Note that each of the first jumper board 102 and the second jumper board 104 can be disengaged from the connector array 108 and reengaged with any of the slots of the connector array 108. Each of the jumper boards 102, 104 also include a multiplexer/switch 106, as is known to those of skill in the art.

The first jumper board 102 is connected to a first network interface card (NIC) 114 via the first of the six slots connecting the first jumper board 102 to the connector array 108. The second of the six slots is connected to a first multiplexer 122 of Node One 218. Node One 218 includes two CPU slots 226, 228, but only CPUO slot 228 has an active and/or installed CPU. CPU1 slot 226 of Node One 218 is connected to the first jumper board 102 via the first multiplexer 222. In this configuration, the first multiplexer 222 prevents the CPU1 slot 226 from connecting to the first jumper board 102, by selecting CPU0 228 slot instead. The remaining four slots of the connector array 108 connected to the first jumper board 102 are in communication with a first GPU array 110.

FIG. 7 illustrates a block diagram of an example computer system 700. A computer system of the subject disclosure can be any of various central processing unit (CPU) architectures such as ×86, Acorn RISC Machine (ARM), Microprocessor without Interlocked Pipeline Stages (MIPS), etc. The example computer system 700 has an ×86 CPU architecture. The computer system 700 includes a processor 740, a network interface 750, a management controller 780, a memory 720, a storage 730, a BIOS 710, a northbridge 760, and a southbridge 760.

The computer system 700 is, for example, a server (e.g., a server in a server rack of a data center) or a personal computer. The processor (e.g., central processing unit (CPU)) 740 is a chip on a motherboard that retrieves and executes programming instructions stored in the memory 720. The processor 740 is a single CPU with a single processing core, a single CPU with multiple processing cores, or multiple CPUs. One or more buses (not shown) transmit instructions and application data between various computer components such as the processor 740, memory 720, storage 730, and networking interface 750.

The memory 720 includes any physical device used to temporarily or permanently store data or programs, such as various forms of random-access memory (RAM). The storage 730 includes any physical device for non-volatile data storage such as a HDD or a flash drive. The storage 730 can have a greater capacity than the memory 720 and can be more economical per unit of storage, but can also have slower transfer rates.

The BIOS 710 includes a Basic Input/Output System or its successors or equivalents, such as an Extensible Firmware Interface (EFI) or Unified Extensible Firmware Interface (UEFI). The BIOS 710 includes a BIOS chip located on a motherboard of the computer system 700 storing a BIOS software program. The BIOS 710 stores firmware executed when the computer system is first powered on along with a set of configurations specified for the BIOS 710. The BIOS firmware and BIOS configurations are stored in a non-volatile memory (e.g., NVRAM) or a ROM such as flash memory. Flash memory is a non-volatile computer storage medium that can be electronically erased and reprogrammed.

The BIOS 710 is loaded and executed as a sequence program each time the computer system 700 is started. The BIOS 710 recognizes, initializes, and tests hardware present in a given computing system based on the set of configurations. The BIOS 710 performs self-test, such as a Power-on-Self-Test (POST), on the computer system 700. This self-test tests functionality of various hardware components such as hard disk drives, optical reading devices, cooling devices, memory modules, expansion cards and the like. The BIOS addresses and allocates an area in the memory 720 in to store an operating system. The BIOS 710 then gives control of the computer system to the OS.

The BIOS 710 of the computer system 700 includes a BIOS configuration that defines how the BIOS 710 controls various hardware components in the computer system 700. The BIOS configuration determines the order in which the various hardware components in the computer system 700 are started. The BIOS 710 provides an interface (e.g., BIOS setup utility) that allows a variety of different parameters to be set, which can be different from parameters in a BIOS default configuration. For example, a user (e.g., an administrator) can use the BIOS 710 to specify clock and bus speeds, specify what peripherals are attached to the computer system, specify monitoring of health (e.g., fan speeds and CPU temperature limits), and specify a variety of other parameters that affect overall performance and power usage of the computer system.

The management controller 780 is a specialized microcontroller embedded on the motherboard of the computer system. For example, the management controller 780 is a baseboard management controller (BMC). The management controller 780 manages the interface between system management software and platform hardware. Different types of sensors built into the computer system report to the management controller 780 on parameters such as temperature, cooling fan speeds, power status, operating system status, etc. The management controller 780 monitors the sensors and has the ability to send alerts to an administrator via the network interface 750 if any of the parameters do not stay within preset limits, indicating a potential failure of the system. The administrator can remotely communicate with the management controller 780 to take some corrective action such as resetting or power cycling the system to restore functionality.

The northbridge 760 is a chip on the motherboard that can be directly connected to the processor 740 or is integrated into the processor 740. In some instances, the northbridge 760 and the southbridge 760 is combined into a single die. The northbridge 760 and the southbridge 760, manage communications between the processor 740 and other parts of the motherboard. The northbridge 760 manages tasks that require higher performance than the southbridge 760. The northbridge 760 manages communications between the processor 740, the memory 720, and video controllers (not shown). In some instances, the northbridge 760 includes a video controller.

The southbridge 760 is a chip on the motherboard connected to the northbridge 760, but unlike the northbridge 760, need not be directly connected to the processor 740. The southbridge 760 manages input/output functions, such as Universal Serial Bus (USB), audio, serial, BIOS, Serial Advanced Technology Attachment (SATA), Peripheral Component Interconnect (PCI) bus, PCI eXtended (PCI-X) bus, PCI Express bus, ISA bus, SPI bus, eSPI bus, SMBus, of the computer system 700. The southbridge 760 connects to or includes within the southbridge 760 the management controller 760, Direct Memory Access (DMAs) controllers, Programmable Interrupt Controllers (PICs), and a real-time clock. In some instances, the southbridge 760 directly connects to the processor 740, such as in the case where the northbridge 760 is integrated into the processor 740.

The networking interface 750 is any interface that supports wired or wireless Local Area Networks (LANs) or Wide Area Networks (WANs), such as Ethernet, Fibre Channel, Wi-Fi, Bluetooth, Firewire, the Internet, etc. For example, the networking interface 750 can include a network interface controller (NIC) for Ethernet. Ethernet has been the most widely used networking standard for connecting computers in both Local Area Networks (LANs) and Wide Area Networks (WANs). Ethernet defines a number of wiring and signaling standards for the physical layer (PHY), through means of network access at the Media Access Control (MAC)/Data Link Layer, and through a common addressing format. Ethernet enabled devices typically communicate by transmitting data packets, which comprise blocks of data that are individually sent and delivered.
